2 Claims.

5 ter indicated by means of which an ordinary floor may be provided witha surface upon which ice skating may be done.

Another object of the invention is the provision of a covering of thecharacter indicated upon which dancing may also be done.

Other objects will appear hereinafter.

The invention consists in the floor covering hereinafter described andclaimed.

In making up the floor covering a mixture is first provided ofingredients as follows: hyposulphite of soda NaQSZOZBHzO, 10 quarts;sodium borate, 42 ounces; sodium bicarbonate, 14 ounces; sodium fluorideNaF'l, 14 ounces, parafiine /2 pound.

These ingredients are mixed together and heated until they boilwhereupon the mixture is poured upon .the floor to be covered andallowed to solidify. The quantity of ingredients above specified will befound to be suflicient to cover thirty square feet of floor.

As will be noted, the bulk or base of the preparation consists of sodiumhypo-sulphite and the function of the sodium borate, sodium bicarbonate,and sodium fluoride are to so harden the same as to adapt it to use withice skates, the

sodium borate and fluoride being particularly effective for thispurpose. The paraf'une wax tends to provide a smooth surface and whensaid surface is properly polished, in dancing or otherwise, will alsoserve as a suitable dancing surface or floor.

I have found that the hyposulfite of soda, the sodium bicarbonate andthe parafiine are the most important ingredients and will of themselvesprovide a satisfactory floor covering, but that the addition of theother ingredients specified some- 5 what improve the consistency andskating qualities of the cover. I have also found that it is practicallyessential to include from to 94% by weight of the hyposulfite, from 5%to 15% by weight of the sodium bicarbonate, and from 1% 10 to 5% of theparaffine, depending upon the moisture content in the atmosphere inwhich the floor covering is to be used.

While I have set forth in detail the preferred ingredients andproportions, these are capable of 15 some variation and modificationwithout departing from the spirit of the invention. I therefore do notwish to be limited to the precise details disclosed, but desire to availmyself of such variations and modifications as fall within the scope ofthe appended claims.

I claim:

1. A floor covering composed of ingredients mixed together substantiallyin proportions as follows: hypo-sulphite of soda, l0 quarts; sodiumborate, 42 ounces; sodium bicarbonate, 14 ounces; and sodium fluoride,14 ounces.

2. A floor covering composed of ingredients mixed together substantiallyin proportions as follows: hypo-sulphite of soda, 10 quarts; sodium 30borate, 42 ounces; sodium bicarbonate, 14 ounces; sodium fluoride, 14ounces; and par-afiine wax, /2 pound.
